Justification:
This species is listed as Least Concern in because of its wide distribution, presumed large population, occurrence in a number of protected areas, tolerance to some degree of habitat modification, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

Abundant. Rare in Argentina (Barquez pers. comm.). Large roosts of hundreds of bats have been reported. They may also roost in smaller groups of up to 30 individuals and forage at night in groups of 5 to 15 animals (Mulheisen and Berry 2000).

Hollow trees, caves, piscivore, can eat aquatic insects. Observed in groups larger than 30 individuals in Brazil (Barquez 1999). They roost near streams, coastal marine habitats, major river basins, or other moist places. Bachelor males roost apart from females. Males residing with female groups stay for two or more reproductive seasons (Mulheisen and Berry 2000). Females bear a single young each pregnancy. This species tends to have pregnancies occuring from September until January, and lactation is first seen in November and continues until April. This is a general pattern, however, and it can vary with geographical location. Reproduction corresponds to seasons of greatest food availability (Mulheisen and Berry 2000).

There are no major threats throughout its range. In Guatemala fishfarmers are killing this species (Cajas pers. comm.). Water bodies pollution (Armando Rodriguez pers. comm.). In Belize the water level changed and restricted the range (Miller pers. comm.). Deforestation (Uribe and Castro-Arellano, 2005).
